Megrim:Typically, these are recurring headaches affecting one or both sides of the head. Migraines may be accompanied by symptoms such as nausea, vomiting, heightened sensitivity to light (photophobia), increased sensitivity to sound (phonophobia), dizziness, blurred vision, and other disturbances. Some migraines may occur without a headache and might be preceded by an aura.The words "megrim" and "migraine" share both meaning and etymology. In Latin and Greek, pain on one side of the head was termed "hemicrania" or "hemikrania," derived from the Greek "hemi-" for "half" and "kranion" for "skull." The French adapted this to "migraine," a variant of "hemicrania," to describe the same condition. English adopted "migraine" twice from French. In the 14th century, the French term was altered to "migreime," leading to the word "megrim." In the 15th century, the French "migraine" was borrowed again without changes to its spelling. Today, "megrim" and "migraine" can be used interchangeably.Additionally, "megrim" can refer to vertigo or dizziness and, outside a medical context, can denote a whimsy or a state of low spirits.
